Steel Floor Decking Systems Explained
Steel floor decking (also known as composite floor decking or metal floor decking) is used as permanent formwork for reinforced concrete slabs. It provides structural support during construction while forming part of the finished floor system.
Composite floor decking systems combine profiled steel sheets with concrete to create a high-strength, lightweight solution ideal for modern construction. These systems are widely used in commercial buildings, offices, hospitals, schools, and multi-storey developments.
Composite Floor Decking Profiles & Systems
Our range of composite floor decking sheets includes both shallow and deep profile systems designed to suit a wide variety of structural requirements. From standard steel floor decking for multi-storey buildings to long-span solutions for high-load applications, we supply profiles to meet every project specification.
Metfloor 55
Engineered for shallow slab construction, MF55’s dovetail re-entrant profile delivers excellent composite floor decking action, fire resistance, and acoustic performance. Ideal for residential, and refurbishment projects.
Metfloor 60
Designed for longer spans and reduced concrete volume, MF60 steel floor decking offers excellent fire performance and faster installation, making it ideal for high-rise residential and commercial builds.
Metfloor 80
A robust floor deck profile offering superior spanning capability and reduced slab weight. MF80 composite floor decking is perfect for multi-storey car parks, industrial floors, and larger commercial projects.
Comflor 46
A compact and efficient steel floor decking system, CF46 is ideal for smaller-scale projects, refurbishments, and sites with restricted access needing lightweight structural solutions.
Comflor 51
Combining spanning efficiency and reduced concrete usage, CF51 composite floor decking is suited for modern office developments, residential towers, and mixed-use buildings needing sleek structural floors.
Comflor 60
Engineered for strength and sustainability, CF60 steel decking provides efficient spanning, optimised concrete depths, and excellent fire resistance, perfect for large commercial floors.
Comflor 80
A heavy-duty composite floor decking, CF80 delivers outstanding spans and load capacities, ideal for demanding industrial, commercial, complex architectural projects.
Comflor 100
Designed for maximum unpropped spans and slab depths, CF100 steel floor decking is the solution for projects needing wide open floorplates and reduced structural costs.
Long Span 220
Our deepest floor decking profile, Long Span 220 steel floor decking is engineered for heavy loads and long spans, ideal for multi-storey car parks, infrastructure, and complex composite slabs.
R51+
A re-entrant composite floor decking designed to achieve shallow slab depths while maintaining excellent fire and acoustic performance. R51 is commonly specified on first floors where storey height control and a flat soffit finish are important design considerations.
TR60+
An economical trapezoidal steel floor decking offering fast installation and reduced concrete volume. TR60 is well suited to first-floor construction where programme speed, material efficiency, and reliable un-propped span capability are required.
TR80+
A deep trapezoidal composite floor decking designed for long un-propped spans and efficient structural layouts. TR80 is ideal for first-floor applications where reducing secondary steelwork and maintaining strong fire and acoustic performance is a priority.
